As abelhas (Hymenoptera: apoidea) de Mato Grosso do Sul: um checklist da fauna estadual

Abstract

The state of Mato Grosso do Sul (MS), with its vast and diverse landscape, including the Atlantic Forest, Pantanal, and Cerrado biomes, presents a wide range of physiognomies that directly influence insect diversity. However, these biomes are under increasing anthropogenic pressure, negatively affecting biodiversity and reinforcing the need to expand our knowledge of the state’s biota. Among the most ecologically important insect groups are bees, which play essential roles in ecosystem functioning, particularly through pollination. In this study, we compiled data on the richness and distribution of bee fauna of Mato Grosso do Sul, gathering occurrence records and characterizing sampling patterns. We assembled a database of specimens deposited in scientific collections, searched the literature, and used the speciesLink platform. We georeferenced collection sites and conducted a taxonomic validation with specialists. Using QGIS, we generated heat maps (KDE) to visualize sampling concentration and species richness. In total, we gathered information on 375 species, including 40 new records for the state and some species previously unknown to Brazil. The analysis showed that sampling efforts are concentrated in the western portion of MS, particularly near the Pantanal-Cerrado border, where species richness is highest. These results reveal pronounced sampling gaps across the Mato Grosso do Sul.
